When we can buy energy savings from our customers at a lower cost than we can buy traditional supplies of electricity or natural gas, it’s a least cost resource that helps keep future electricity and natural gas supply costs lower than they would otherwise be. Through Efficiency Plus, we offer a variety of rebates to help improve the energy efficiency of your existing commercial or industrial building.

* Electric rebate programs for South Dakota have ended for 2016. Natural gas rebate programs for South Dakota are currently available.
